Q:How do we calculate the length of a drill for a bored pile drill?: There are two main types of drilling rigs: rotary drilling machine and impact drilling machine. The bit of rotary drill is divided into three kinds of scraper drill: suitable for quicksand and silt layer. Only the diameter and weight limit, no length limit cone drill: suitable for soft stone and hard soil. There is no length limited hob drill: suitable for hard rock layers. There are weight limit and hob arrangement, hardness requirements above, there is no drill length requirements. Impact drill: it is to use the weight of the drill to squeeze the soil into the hole, and the hole of the rock is also to use the bit itself to destroy the rock structure surface into holes. Only the weight on bit (according to the requirements of classification of rock hardness determine bit weight, diameter of 2-2.5 meters in the drill hole, the weight of at least 10 tons; 1.5-2 meters, bit weight of about 5 tons, 1.5 meters below 3 tons. For impact drilling, the length of the drill has a certain requirement, usually 1.8-2.5 meters high. Because the longer the drill bit, the stronger the impact drilling guidance function, the smaller the possibility of partial hole, hammer and hammer, the higher the standard of drilling. There are no rules and regulations, and you can succeed by experience.

Q:What drill is used for machining holes with a diameter of 3mm?: At the same time, it is difficult to guarantee the absolute symmetry of the two main cutting edges because of the small bit. Generally, it is necessary to control the secondary angle of the blade edge at 6 degrees to 8 degrees. The speed is between 1000~1500, and the feed is low, otherwise the drill is easy to break or damage. The emulsion should be cooled during processing.

Q:Tap with 5 taps. How many drills are drilled?: Calculation formula:The workpiece is a brittle material (cast iron, bronze, etc.): the bore diameter is D=d- (1.04 to 1.08) tThe workpiece is made of plastic material (steel, copper, etc.): bore diameter is D=d-tD: nominal diameter of thread, t: pitch, unit: mm

Q:What are the brands of homemade twist drills?: General twist drill rolling and grinding, high quality grinding, I used, there are good brands in the processing of steel parts on the whole: drill, drill Gongquan full amount, mine drill, drill the Far East

Q:How to install expansion screw? How big is the screw? What size is it? Or what? How do you see the size?: Expansion screws have models, usually M6, M8, M10, M12 and so on. M6 only refers to the diameter of the nut and screw. If drilling, the drill bit should be selected according to the diameter of the expanding part of the expansion tube. We usually use larger size drills.

Q:What are the tools, drills, and any of the machine tools made of?: High speed steel means containing more tungsten, chromium and aluminum alloy elements such as the tower of metalwork of steel, commonly known as steel or stainless steel.The machine is characterized by simple manufacture; high hardness (63 ~ 66HRC), wear resistance and heat resistance (about 600 - 660 C); have sufficient strength and toughness; have good craft; can bear greater impact; tool manufacturing complex shape, such as special lathe tool, milling cutter and drill, broach and gear cutter; but notIt can be used in high speed cutting. Grades and properties of commonly used high speed steel.The hardness of high speed steel after quenching is HRC63 ~ 67, and the red hard temperature is 550 ~ 600 DEG C, and the allowable cutting speed is 25 ~ 30m/min.The bending strength and impact toughness of high speed steel is high, can be cast, forging, welding, heat treatment and machining, has good grinding performance, the grinding quality is high, so it is used to manufacture complex shape of tools, such as drill, reamer, milling cutter, and also used for low speed machining tool and forming turning tool.Commonly used high-speed steel grades are W18Cr4V and W6Mo5Cr4V2 two.

Q:The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?: If the opening is often marked with the vertical line, then along a circle hole, knocking out the middle can.

Q:Twist drill 200mm deep bore, what does the drill grind?: A standard twist drill is a very common drill tool. The utility model has the advantages of simple structure and convenient sharpening, but the grinding method is really good, and the method and the skill of grinding are well mastered. Factories also have such a situation, the work of more than ten years of workers, grinding well, twist drill also quite a lot. What is the reason for this? The key is methods and techniques. If the method is mastered, the problem will be solved.

Q:What kind of drill bits are used in glass drilling?: Drill glass has special drill bits, steel sand drills.Use a twist drill to drill glass. The glass is easily broken and cracked. If you must use a twist shape, buy a milling cutter. It is not easy to use a milling cutter to drill holes in glass.If you buy high-speed steel twist drill is really qualified high-speed steel material, you can drill through the glass, if high-speed steel is not possible, you may consider carbide steel.Small steel sand drill bit will be about 3 yuan, cheaper, it is better to buy this thing.Of course, the diamond is also OK, just so expensive.

Q:What is the cause of the drilling mud bit?: Geological factors: the drilling for upper diagenetic ooze, easy to paste on the bit surface, bit balling caused by compaction after formation of shale; although diagenesis, but easy dispersion, the borehole mud or solid content increased, adsorbed on the surface of drill bit by bit balling; or the strata containing dispersed gypsum, resulting in mud pollution, harmful solid mud in difficult to remove, the probability of bit balling is increased; the formation of high permeability, under pressure, harmful solid phase adsorption within the wellbore and cuttings did not timely carry out the formation of thick mud cake, while tripping in PDC below the drill bit caused by the accumulation of bit balling.
